The first day back from a national holiday may be the best or the worst time to initiate coverage on a stock, depending on how badly you want, or don’t want someone to see the research.

This morning, a few recently public companies received initiation reviews, largely positive, by their underwriters.

Yandex (YNDX), the Russian search engine that went public on May 24th, is up 41 cents, or 1%, at $36.16 in early trading, after the stock was started at Buy, or the equivalent, by Piper Jaffray, Deutsche Bank, Morgan Stanley, Pacific Crest, and Oppenheimer & Co. Goldman Sachs started the stock at Neutral.

Freescale Semiconductor (FSL), the chip maker that is formerly an arm of Motorola, and that came public on May 26th, is up 71 cents, or almost 4%, at $20.46, after the stock was initiated at Buy or the equivalent by Piper Jaffray, Citigroup, Deutsche Bank, Barclays, Oppenheimer, Credit Suisse, JP Morgan, Sanford Bernstein, and Gleacher & Co.

And The Active Network (ACTV), which operates a network of sites for online communities, today was initiated at Buy or the equivalent by Citigroup, ThinkEquity, Merrill Lynch, Stifel Nicolaus, and RBC Capital.
